Title: Semiconductor device and fabrication thereof
Inventor: MIURA HIROTOMO
IPC: H01L29/78
Filed: 1998-09-28
Abstract: PROBLEM TO BE SOLVED: To facilitate control of heat treatment in silicidation through a simple method without increasing the number of steps or complicating the structure and to decrease the resistance of a conductive layer represented by a gate electrode sufficiently even at the time of mass production.

Title: Television receiver
Inventor: KATAGIRI TAKAHITO
IPC: H04N11/20
Filed: 1989-10-23
Abstract: PURPOSE:To output a high-fidelity signal, which can be recorded by a high- picture quality VTR for NTSC or a normal VTR, by providing a means to convert the scanning line number of the high-fidelity signal to the scanning line number of the NTSC system. CONSTITUTION:The high-fidelity signal to be outputted from a MUSE video processing circuit 181 is a 2:1 jump scanning signal, for which an aspect ratio is 16:9 and the number of scanning lines is 1125, and a Y signal and a C signal are basically frequency-separated. A scanning line number converting circuit 31 converts the high-fidelity signal to a 2:1 jump scanning signal for which the number of scanning lines is 525 while maintaining the aspect ratio as it is. The format of this signal is same as the format of a EDTV signal to be outputted from a three-dimensional Y/C separating circuit 131 of an EDTV processing circuit 13 excepting for the aspect ratio. Thus, the high-fidelity signal, for which the number of scanning lines is converted by the scanning line number converting circuit 31, can be recorded by the high-picture quality VTR. The frequencies of the Y and C signals are multiplexed by a frequency multiplexing circuit 35 and the high-fidelity signal can be obtained to be recorded by the normal VTR.

Title: Production of abrasion-resistant sodium percarbonate having high rate of dissolution and sodium percarbonate produced thereby
Inventor: RIYUUDEIGAA SHIYUTSUTE
IPC: C01B15/10
Filed: 1994-11-08
Abstract: Although sodium percarbonate obtained by crystallisation processes has a high dissolving speed (rate of dissolution), it has at the same time a moderate abrasion resistance. According to the invention, the abrasion resistance can be increased by spraying the percarbonate with an aqueous sodium percarbonate solution or an aqueous hydrogen peroxide solution and an aqueous sodium percarbonate solution in a fluidised bed at a fluidised-bed temperature in the range from 40 to 95 DEG C. Sodium percarbonate prepared according to the invention and having an amount of shell (encapsulation layer) between 3 and 10% by weight has a high abrasion resistance with at the same time a high dissolving speed.

IPC: H01M8/06
Filed: 1991-10-22
Abstract: PURPOSE:To use a heat energy of steam obtained by a steam separator high- pressure steam separated by the steam separator for the external supply steam, and taking low-temperature and low-pressure steam obtained by a flush tank for reformation steam. CONSTITUTION:Steam separated by a steam separator 2 is supplied through pipings 14 to the external to be external supply steam for driving a double effect type suction freezer, for example. The external supply steam supplied to the double effect type suction freezer becomes return water after it is cooled to be returned to the steam separator again through pipings 15. By heating water supplied through pipings 17 to an exhaust air system heat recovering heat exchanger by heat exchange with high-temperature exhaust air 16 discharged from an air pole 4, external supply hot water is supplied through pipings to the external. The high-temperature and high-pressure steam separated from the separator 2 is thus taken for the external supply steam, while low- temperature low-pressure steam from a flush tank 20 is taken for reformation steam.

Title: Low-noise output driving circuit
Inventor: HASHIMOTO MASAMI
IPC: H03K17/16
Filed: 1991-10-22
Abstract: PURPOSE:To provide the low-noise output driving circuit. CONSTITUTION:A 1st driving circuit 10 which has an N type MOSFET 15 at its positive electrode and a P type MOSFET 16 at its negative electrode and a 2nd driving circuit 11 of normal constitution having a P type at its positive and an N type at its negative electrode are prepared and a delay control circuit 12 performs control so that the 1st driving circuit 10 operates first and the 2nd driving circuit 11 operates next. This constitution uses the N type at the positive electrode of the 1st driving circuit 10 and the P type at the negative electrode, so the output level does not rise up to a power supply potential and then reaches the power supply potential by the 2nd driving circuit 11. This method suppresses a transient current at the time of output variation and eliminates overshooting and undershooting. Consequently, the transient current is made small and a noise is reduced. Further, the output level varies in two stages, so the power consumption of the charging and discharging of a capacitive load is reducible.

Title: Interferometer with noise preventing function
Inventor: ASANO MITSUE
IPC: G01B11/30
Filed: 1995-09-27
Abstract: PROBLEM TO BE SOLVED: To measure interference fringes with high accuracy even if a surface for inspection is low in reflectance by providing a transmitted-light-sensitive means for reducing the intensity of a light beam transmitted through an alignment screen. SOLUTION: An ND-filter film 32 that acts to reduce transmitted light, e.g. with a light transmission rate of about 2%, is bonded to the upper surface 30c of an alignment screen 30, and a hole 32a with the same diameter as a light through hole 30a in the alignment screen 30 is formed in the ND-filter film 32. Therefore, light scattered from a beam spot B on the alignment screen 30 is significantly reduced in intensity after being transmitted through the ND- filter film 32, thus preventing noises from being superimposed on an image of interference fringes as the scattered light arrives at the photographic surface of a CCD camera 26. Thus even if a surface 4a to be inspected is low in reflectance, the interference fringes can be observed and measured with accuracy.

Abstract: PURPOSE:To facilitate mounting and demounting of a cup having any size by a method wherein a cup holder is provided with a contact part making contact with the inner wall of the cup, a clock part to lock the flange part of the cup, a contact part making contact with the outer wall of the lower flange part, and a handle part to which a hand is locked, and is formed by resin having resilient nature. CONSTITUTION:A flange part 4 of a cup 1 is locked to a lock part 9, a peripheral wall 3 of the cup 1 is held between the nip formed by a contact part 6 of a holder 5 and a resilient part 10 having the lock part 9. By supporting an outer wall 3B of the cup 1 by a contact part 8, the holder 5 is mounted to the cup 1. Thus, irrespective of the size of the cup 1 and the diameter and height of the cup 1, the holder 5 can be firmly mounted, and when the cup is full of liquid, it can be held stable. Since insertion of the flange part 4 into a containing groove 11 and press downward of the holder 5 suffice for mounting of the holder, the holder can be mounted easily. In this case, since the resilient part 10 is arcuately inflated toward the handle part 7 side, insertion of the flange part 4 is facilitated, contact of the lock part 9 with an outer wall 3B of the lower flange part 4 is strengthened, and the cup 1 is difficult to part from the holder.
